BANK-NOTE TESTER.

Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed February 18, 1909. Serial No. 478,703.

To all whom it may concern:

Be it known that I, ISABELLA COHEN, a citizen of the Empire ofAustria-Hungary, residing in New York, in the borough of Manhattan,county and State of New York, have invented certain new and usefulImprovements in Bank-Note Testers, of which the following is aspecification.

This invention relates to an improved tester or apparatus for testingthe genuineness of bank-notes, said apparatus being intendedto be usedby banks and other institutions for quickly distinguishing a forged orspurious'bank-note from a genuine one; and for this purpose theinvention consists of a bank-note tester which comprises asupporting-bar provided with a handle, a magnifying-lens, swiveled tothe front-end of said bar, a movable stand adapted to slide on thesupporting-bar, and means on said stand for holding the genuine and thespurious bank-notes side by side so as to compare {hem by lookingthrough the magnifyingens.

The invention consists further of certain details of construction whichwill be fully described hereinafter and finally pointed out in'theclaims.

In the accompanying drawings, Figure 1- 'tester,-which bar is providedwith a handle it at the under-side. To the front-end of thesupporting-bar a is applied a magnifyingpermits the lens to be turned onthe axis of 1ts post, as required, in looking at special portions of thebank-notes to be examined.

On the rear-portion of the supporting-bar I the swivel-connection of theThe. swivel-connection of the a is guided a transverse frame or stand 6on which a genuine and spur ous bank-note can be placed .s1de-by-s1de,said stand being guided by a recess of its base-rail b on thesupporting-bar a and held thereon by 'a spring-actuated friction-deviceb having a handle I), as shown in Fig. 3. The supporting-frame orstand?) is formed of two parts 6* which are connected'by the baserail 6and agrooved rail d on which the bank-notes can be supported side-byside, the genuine one preferably on the left-hand and the spurious oneon the ri ht-hand side, or. vice versa. Each part b 'IS provided with abutton or knob e at its lower end for moving the stand I) convenientlyforward or backward on the rail (1. The lower edges of the bank-notesrest in the groove of the transverse rail (1, and against the two standsand are held at the upper edges by hooks 6, said hooks being connectedby means of two pivot-links 6 with the upper ends of springactuated arms0 which are bent into springcoils at the lower part and attached toacross-bar of the stand. The hooks 0 yield by their spring-connectionwith the stand sufficiently to engage the upper edges of the bank-notes,asindicated in dotted lines in Fig. 2. Midway between the stands isarranged a separating device 7, which is made in the shape of a wireloop having a pointed end, which latter is inserted into a hole at thecenter of the base-rail. The-separating device servesas an abutment forthe ends of the bank-notes but keeps them separated from each other attheir meeting edges.

For examining a spurious bank-note it'is placed in position on onestand, with its lower edge inserted into the grooved rail of the sameand the inner edge placed against the separating device The upper edgeis then placed in engagement with the yielding hook e. The genuinebank-note is then placed side-by-side with the spurious one on thesecond stand and held thereon by the yielding hook, in the same manneras-the spurious bank-note. The bank-notes are then compared by means ofthe magnifyinglens, which is. turned on its swivel-connection with thesupporting-bar in the direction of one bank-note and then in thedirection of the other, so that the differences in the bank-notes can bereadily detected and the spurious or forged bank-notes readily detected.

The device forms a convenient means for 'detectingiforged' bank-notes tobe used by] banks, moneyed institutions, {and wholesalebusiness-concerns in which a large number of'bank-notes'are handled.

Ha'ving ;thus described my invention, I

claim as new, and desire to secure by Letters Patent; 1

.1. In a-bank-note tester, a bank-note supporting frame comprlsing abase-rail, two

separate upright stands on the same,' a

' grooved rail connect-ingsaid stands for supporting the lower edges of.the bank'-notes, and yielding hooks for engaging over the npper fedgesof thebank-notes. 2; y In a bank-note tester,' ,'abank-notesupporting'frame comprising a basewail, two

separate upright stands .on the; same, a

edges of the bank-notes, and a separating device located midway betweenthe stands.

3. In a bank-note tester, a bank-note supportmg frame comprising abase-rail, two separate upright stands 011 the same, a grooved rail 1connecting said stands and 'spacedzabove said base-rail spring pressedarms secured to the stands, 11nks connecting the free ends of thearms,hooks secured to the links for engaging over the upper edge of abank-note, and a separating device 10- cated'on thebase-rail andextending above the grooved rail midway between the stands. Intestimony, that I claim the foregoing as my invention, I have signed myname in presence of two subscribing witnesses.
